Build Your Own Assay Tools

Complete Set of Tools to Build Your Own Stable Cell lines and Cell-Based Assays

Take advantage of DiscoverX’s robust proprietary Enzyme Fragment Complementation (EFC) technology to develop your own stable cell lines and cell-based assays to study protein-protein interactions, compound-target engagement, cytotoxicity, protein translocation, and much more. Design your own workflows and utilize engineered parental cell lines, retroparticles, and plasmid vectors to introduce your own target of interest and create cell-based assays for multiple applications.

 

Make Your Own Cell-Based Assays to Study β-Arrestin Recruitment

Watch this 30-minute webinar to learn how to make your own cell-based assays to analyze β-arrestin recruitment in any cell type. Use these assays to analyze tissue-specific variations, compare ligand responses in different species (orthologs), evaluate specific GPCR mutants that cause disease, or study non-GPCR β-arrestin-interacting proteins.

Easily Make Your Own Compound-Target Engagement Cell-Based Assays


InCELL Pulse™ Target Engagement Starter Kit

Develop cellular InCELL Pulse compound-target engagement assays to measure inhibitor cellular potency against user-defined protein targets of interest. These assays apply EFC and ligand-dependent thermal stabilization of target proteins such as protein kinases, methyltransferases, and hydrolases. Employ the simple protocol with minimal hands-on time to obtain quantitative inhibitor EC50 values in a the native cellular environment.
